I went to Harbor Freight yesterday (they get their trucks on Mondays) and was able to get 5 pkgs of blades---total cost $8.10 for 10 blades. I also went online and ordered 20 packages. The total cost there was $40.48 but still not a bad price for 40 blades. However, the warehouse told me that they were out of them and the back order wouldn't be in until the first week in October. I told them to order more because they were going to be selling like hotcakes since quilters had found them.
